摘要: 从压裂裂缝无量纲井底压力典型图版出发,结合裂缝性油藏广义Vogel方程的研究成果,建立了裂缝性油藏压裂井不同生产天数流入动态曲线的求解方法,通过实例验证了研究结果的可靠性,并分析了不同无量纲裂缝导流能力时不同生产天数的流入动态曲线的变化规律。结果表明,无量纲裂缝导流能力高时,油井的初期产油量大,但递减幅度大,稳产难度大,选择合理的无量纲裂缝导流能力,对火山岩裂缝性油藏的高效开发有益。

Abstract: From the non-dimensional typical chart of bottom hole pressure during fracturing, combining with the generalized Vogel equation for fractured reservoirs, the article establishes a solving method of the inflow performance curves with different producing days in fractured reservoir fracturing wells. The reliability of the research results are verified by an example and the variations of the inflow performance curves with different producing days and different non-dimensional fracture conductivity are analyzed. The results show that when the non-dimensional fracture conductivity is large, the initial well production is high but the production decline is large and it is difficult to maintain the well production. Therefore, selecting a reasonable non-dimensional fracture conductivity value has practical significance for efficient development of fractured volcanic reservoirs
